I To all whom it may. concern;

V is a detail view of the balance-Valve.

Be it known that I, EDMUND B. LUDWIG, a citizen of the United States of America, residing at Kansas City, in the county of J ackson and State of Missouri, have invented certain new and useful Improvements in Carbureting-Lamps; and I do hereby declare that the followin is. a full, clear, and exact description of t e invention, suchas will enable others to makeand use the same, reference being had to the accompanying drawings, forming a part of this specification.

The objects of my invention are, first, a'

self-generating lamp for the burning of the hydrocarbons and which is serviceable for the illumination of dwellings, public halls, or thoroughfares; second, to sub ect the hydrocarbon and the atomizing fluid to opposing pressures and produce thereby a quicklygenerated vapor; third, to arrangethe valves contorlling the supply of the hydrocarbon and the atomizing flm in such a manner that the coglplete cuttin off of the former will admit a. 1 supply 0 the latter, and vice versa; fourth, to enable the generated gas to draw its own supply of free air for combustion; fifth, to divert the heat from the gas in combustion to the gas-generator.

The invention consists in the novel construction and combination of parts, such as will first be fully described and then specificall pointed out in the claims.

the drawings, Fi e 1 is a side view. of the novel self generatmg gas-lamp embodying my invention shown in an elevated suspended position, also showing the pressure tank for the hydrocarbon the supplypipes for thecompressed air and the hydrocarbon leading from the tank to the lamp, and the air-compressor. Fig. 2 is a vertical sectional view of the lamp as seen in Fig. 1, the view being lgiken upon the section-line a: a: of

- Similar letters of reference indicate corresponding parts in all the figures of the drawfi eferring the drawings, A represents closes the jet-mixm passage 1). portion 1) of the casing, extending an opposite direction to the portion 12 is an ex central portion or body I) of the casing inor atomizing chamber and is of considerable thickness transversely and extends upwardly above the lineof'the valve-casing and is deflected rearwardl of its vertical axis. Upon the uppler end 0 the I body I) of the casing, in line w1t the forward edge, is a screw-threaded vertical projection b In the body 6, in a vertical line with the opening in the pro'ection 6 is a vertical opening I). U ont e upper end of the body I) in rear of t e projection V, is a vertical screw-threaded opening I) to receive the atafter described. Upon one side of the body 5 is a horizontally-extended integral portion 1?, which is cored out to form the atomizin or jet tube 1)", extendin from its outer en to a position within the ody portion 1), the axial line of said openin 1) extending in rear of the vertical ope The inner end of the opening or atomizlng-tube b is decreasedin size and terminates in a small atomi From the other side of the b0 y ternally-screw-threaded bearing 1), in which is an opening or tube I), nearly of the same size as the o ening b and extending from the outer en L of the bearing in the direction. of said opening, the axial line of the opening b meeting the axial line of the opening I). A flanged plug b closes the o ening b.

' The inner end of the cham r or opening I) communicates with the inner end of the opening I), the end of said opening I) be' contracted in size to form a cone-shape valve-seat b, which valve-seat is in communication with the opening-b, said opening b tachment for suspending the lamp, as hereinbeing increased in width downwardly from b is internally IIO duced in size circumferentially and externally screw-threaded. In a central location to the ends of the valve-casing b is a solid internal part b, in which is a longitudinal o ening I), through which extends the cones aped inner end of the valvestem b, which end'is seated in the valve-seat b. The inner end of the stem 6" is smaller in size than opening I), so as to admit the passage of the air around the stem to the valve-seat b. On said stern b is a valve b", integral with the stem, which is seated in the valve-seat b on the outer end of the bearing b and between said valve b and the solid art 6 is a space I) at sufficient width to e mit of the rearward movement of the vaIve. In the upper portion of the Valve-casin b and extending downwardly within the soi id part b a short distance is a depression or opening I), and upon the'outer side of the casing. extending around said opening, is an internally-screwthreaded projection b. In the upper portion of the solid part b of the casing is a small opening I), the inner end of the opening 1) being contracted in size to form a coneshaped valve-seat. With the outer side of the valve b is connected a needle-valve b, the inner end of which valve extends within the opening I) and to within a short distance of the valve-seat when the valve 1)" is closed. The outer end of the stem 6 is provided with a left-hand screw-thread.

Within the outer end of the valve-casing 1) extends the inner end 0 ofa stem-operating s indle C, in which is a longitudinal screwtiireaded o ening c, the threads being lefthanded an "fitted to receive the left-handed screw-threads of the stem 12" and permit of the movement of the inner end of the stem within the s indle C the requisite distance to open the va ves b and b the valve 1) being already open. Fitted to the outer screwthreaded end of the valve-casing b is a longitudinally-extended cap I), which is internally screw-threaded to Within a short distance of its inner end. In the outer end of the cap I) is an opening b, through which the inner end of the stem-feeding spindle 0 extends. On the stem-feeding spindle C, within the cap b is an annular pro ection c, which occupies the space between the outer end of the valve-casing andthe inner end of the cap 6 and acts as a packing to prevent the escape of the vapor from the valve-casing. I'pon the outer end of the spindle C is a handwhccl 0*. In the upper portion of the horizontally-extended portion of the chamber 6 is a small-sized opening 17 leading to the opening I) for the passage of the gasolene, and upon the outer side of said portion 6 around said opening I), is a'screw-threaded projection b. The lower portion 6 of the atomizing chamber is externally screwthreaded and a couplin D fitted thereto, the lower part of the coup ing being reduced in size and both internally and externally screwthreadcd. l/Vithin the coupling D is a diaemcee should the pressure above be in excess of a back pressure, the area of the opening (1 in the diaphragm (1, through which the vapor passes, eing less than the area of the vapormixing chamber b Fitted to the external lower end of the cou ling D is an annular screw-threaded collar i upon which is an outwardly and downwardly extended flange Secured to the top of the flangsif is an outwardly and downwardly extende reflector G, the under surface of which is made to reflect the light downwardly.

With the internal screw threaded lower end of the coupling D is connected the upper screw-threaded end of the gasenerating tube H, the lower end of whic extends downwardly a sufl icient distance to receive the heat imparted from the heat of the gas in combustion. The lower end of the asgenerator H is externally screw-threa ed, and upon said end is a screw-threaded cap h, having a cone-shaped end 72, in which is a small perforation h for the escape of the generated gas. Within the openmg b of the body portion 1) of the atomizer is a wirecleaning needle-stem I, the extreme lower end of wh ch needle-stem is reduced in size and extends downwardly within the opening k in the cap it in generator H, and upon said end is a needle-point i, which extends loosely within the opening it and acts to permit the passage of the generated gas and to keep the opening free from incrustations. The upper end of the needle-stem I extends a short distance above the projection b and is rovided with a circular enlargement or head if. Upon the projection b is a screw-threaded cap t through which the stem I passes, the space between the cap and nipple receiving the usual packing to prevent the escape of the va or.

ith the outer side of the collar F is connected the upper end of the heat-tube K, which is several times the'circumference of the gas-generating tube H, the lower end of which tube K extendsdownwardly a considerable distance ,below the line of the lower end of the gas-generating tube H to provide for the support of the air and gas mixing receiver or tubes L L and the draft-tube M. In the sides of the tube K are the longitudinal openings k k, which admit of the passage of the heat from the lamp to the gas-generator H. These openings k k are upon each side of the tube K and extend from a, point are wire screens Z 1 secured by the bands Z LII a considerable distance below the collar'F downwardly about one-half the distance toward the lower end of the tube and are of the proper width to give free entrance to the heat. Upon the lower end of tube K is securedby the upwardly-extendin lugs Z l the internally-screw-threaded nec Z connected with the air andgas mixing conductor tubes L L, which tubes extend downwardly in opposite directions and theirouter endsbent in curved lines and extended u wardly a short distan e. The lower end oi the tube K is outward y flaring and rovide d'zwith passages k for the entrance 0 the airfi; Upon the outer endsof the tubes L L to the. outer surface of the tubes. Around tl'es are connected with the horizontally-experforated centrally at h to admit of the partial extension therethrou h of the coneshaped end of the cap 71- on t e lower end of the gas-generatin tube H, the diaphragm servin to cause t e downdraft of the air in the tu e M.

Above the mantles O O and extending from the outer side of the tube K in an outwardly and downwardly inclined direction is a .heat-defiectin plate P, smaller in size than the deflecting-p ate G directly above. This deflectinglate is adjustably connected with the tube I? and diverts the heat from the mantles O O to the gasenerating tube H. In the under side of the ollow air and gas mixing receiver or tubes L L, in which the air mixes with the as, is a threaded coupling Z in which is fitte the upper end of a short screw-threaded tube I, provided with a ca Z in its lower end. Supported by the tube 8 is a globe rest or spider R, which is adjustable on the tube by the screw.

Upon the rest R is a glass globe S, secure by the ins 7" from the lateral movement. The gloiie S is open at the top and bottom, and its top extends upwardly nearly to the inner side of the deflector G. i

T represents a closed tank forthe reception of gasolene, which may be laced in any safe location and supplied with ydrocarbon to about one-half its capacity. Connected with the upper part and side of the tank is a of the extension b valve-casing t, in which is a valve t. With the valve-casing t is connected one end of an air-conducting pipe t the other end of which 'pipe is fitted within the projection 6 on the valve-casing b of the lamp. Upon the side of tank T, near the bottom, is a valve-casing t, in which is a valve t. With the upper part of valve-casing t is connected one end of a small liquid-conductin pipe i the other end of which pipe exten s to and is connected with the rojection b on the extension 6 of the body bof the atomizing-chamii' l f 1 represents an air-pum or su yin compressed air to the tankPT, operdlied b5 the plunger 0). With the lower end of the pump is connected one end of a hose 12 the other end of whichhose is connected with the side of a valve-c'asin 1), located in the side of the tank a short istance below the valve-casing t, and in which valve-casing v is a valve 0 Upon the to of tank T is an airressure-indicator gage 'l he body I) of the atomizing-chamber and the valve-casing b are preferably inclosed by a casing Y, the top y of which extends from beneath the cap 11 and thence outwardly and connected with the vertical sides g", which is cylindrical in shape, the lower end of the sides resting upon the up er side "of the deflector G. The sides 1 o thecasing Y are secured to the outer end of the horizontal extension 12 in the plug 1) of the atomizin chamber 6 by means of the screw y, whic enters the screw-threaded plug in said end In the opposite side of the casing Y is an opening y through which the valve-casing 1) extends. In the screwthreaded opening b in the body portion 1) of the atomizin -chamber is inserted the screwthreaded en of a hook z, the upper end of too which is secured to an eyebolt Z 1n the beam z, from which the lamp is sus ended.

In operation air is supplie to the tank T by the operation of pum V until ressure upon the hydrocarbon wil afiord t e constant flow of the-gasolene for a determinate period of time, the amount of compressed air the valve-stem opens the valve b" and also opens communication from the chamber 1) around the stem with the jet-tube b of the atomizer at the same time the needle-valve b is moved toward the seat I) so far as to not close the o ening. The gasolene in thechamber 6 is orced by the ressure of the air in the tank T throu h t e jet tube or opening I) in comminute quantity or small tilt drops or jets, which are met by the compressed air and the atoms broken up and a vapor formed of air and gasolene, which H, which becoming heated converts the gasolenevapor into a highly-inflammable gas mixing with the air, the generated gas burning in the mantles with an intensity to afford a strong li ht of great illuminating power. The heate gas which passes through the tube M causes a suction of the air around the tube K, which asses within the opening k, thence u ward y on the outer side of the downdra t-tube M, thence downwardly within the said tube, affording the necessary oxygen for complete combustion of the gas. As soon as the gas generating tube becomes heated and the gas generated the spindle C is operated to close the needle-valve b, and thus check the ressure and supply of the air from the tank the air necessary for combustion being drawn within the tube M from the opening is and mixed with the gas in the gas-mixing chamber in tubes L L, the u ward tendency of the heated air in tube meeting the diaphragm k is turned downward.

It is obvious that when the light subsides from the lack of supply of the hydrocarbon to be converted into gas the tendency of the operator is to turn the spindle C to the left, so

. as to admit more hydrocarbon or less air,

thus making the proper mixture. If the 7 light flames out at the top of the globe, the

tendency of the operator is to close the spindle C, thus admitting less gasolene and more air, and thus makin the proper mixture. Normally the needle '2, on the needle-stem I is withdrawn from the opening h in the cap h and held b the cap 1& by friction, and when the opening becomes clogged from any reason the stem I is lowered in position, the needle cleaning the 0 ening in the cap h. The balance-valve E a so regulates the quantity of the vapor necessa to supply the gas-generating tube H. hen the pressure from the amount ofgenerated gas in tube H occurs from the heat, the balance-valve E rises and constantly maintains a balance between the downward pressure of the vapor and the back pressure of the gas, and this balance affords the regulation of the quantity of gas necessary for free combustion and an uninterrupted brilliant light.

The invention provides a safe means of house illumination at little cost. The tank T siaeee being placed in a safe location, ail danger is eliminated. For street illumination the lamp is suspended from any suitable support and the pipes connected in the manner shown. The mode of atomizing the gasolene may be employed for atomizing all liquids with equally satisfactory results, and the valves controlling the vaporizing of the liquid and fluids are adapted to be a plied to the ordinary valve-casing for simiizir purposes.
